摘　　要：本研究提出了一种应用搭接式微热管阵列配合长直肋片作为换热组件的真空管太阳能空气集热–蓄热一体化装置,其集热投影面积为0.51 m^(2)。蓄热材料采用52号工业石蜡,质量为9.8 kg。文中详细介绍了装置的设计、工作原理及其在单独蓄热和单独取热的工况下进行实验测试时的热效应情况。为满足集热器的实际应用需求,实验测试工况选在冬季和过渡季两个对热量需求较大的天气条件进行。此外,文中对取热时空气流速和入口温度对装置放热性能的影响也进行了详细描述。研究结果表明,真空管集热–蓄热一体化装置体现出了突出的蓄/放热性能,实验阶段的平均蓄/取热功率可达294.2 W(576.9 W/m^(2)集热面积)及1041.2 W,过渡季及冬季总效率可达63.2%和56.3%。In this study,a vacuum tube integrated collector-storage solar air heater using lap-joint-type micro-heat pipe arrays and long straight fins as heat exchange component is proposed,and the heat collecting projection area is 0.51 m^(2).No.52 industrial paraffin is selected as heat storage material and has a mass of 9.8 kg.The design,working principle and thermal responses under the conditions of charging only and discharging only are introduced in detail.In order to meet the practical application requirements of the collector,the experimental conditions are selected in the winter and transition seasons,which are two weather conditions with high heat demand.In addition,the effects of air flow rate and inlet temperature on the discharging performance of the device are also described in detail.The results show that the vacuum tube integrated collector-storage solar air heater has experienced outstanding charging and discharging performance.The average charging and extraction power can reach 294.2 W(576.9 W/m^(2) of heat collecting area)and 1041.2 W.The total efficiency in the transition season and winter can reach 63.2%and 56.3%.
